The 24-year old Canadian-born former Holland youth international has signed a season-long loan with the Swans making him the second signing since Michael Laudrup took over after Chico Flores joined earlier today.
"Once the opportunity came along to join Swansea and Michael Laudrup it was a done deal,'' he told the club’s official website. "I didn't have to think twice about it.
"I watched Premier League football every week on the TV last season. I was aware that Swansea are a good footballing side, but they really caught my eye when they beat Manchester City.
"They had a great season and I'm really looking forward to the challenge of playing on a new podium in the Premier League.
"I'm grateful for the opportunity and grateful that the manager has acknowledged me as a player.''
